I can't compile main.cpp in vscode.

    If you don't set up configuration scripts or forget to list all source files in it, then only a single source file will be built and linked into the application. You need to configure VSCode to invoke the compiler and linker with *all* files in your project. Since you're on a macOS system [this guide about using Clang together with VSCode](https://code.visualstudio.com/docs/cpp/config-clang-mac) should be very helpful. – Some programmer dude Sep 23 '21 at 03:54
